For portable (hiking) GPS's, the Garmins are packaged well, pretty good interface and decent reception in cover. The higher-end Etrex models with some Mb storage for map detail are nice if you are hunting or hiking and not really staying on a set trail. My only gripe with the etrex series has been their cold start ability on hillsides/heavy trees and obtaining a fix, usually not an issue if you entered the area with it powered-on and tracking. I haven't tested my Garmin Rhino to extensively yet, but an initial test was not impressive, powering on and starting to walk it failed to gain a fix in basically open-flat terrain, only gaining a fix once I stopped for about 5 minutes. Unacceptable!
We recently purchased a Lowrance iWay 250c for traveling and it is excellent, great interface, reception, routing and decent features for the price (about $250).
It is portable, but doesn't have hiking features like elec compass and easily set waypoints.
